Question

area of rectangle
$a = l \cdot w$
what is the surface area of the three - dimensional figure?
s.a. = \square in.^2
s.a. = 2(6 \cdot 2) + 2(6 \cdot 3) + 2(2 \cdot 3)

Explanation:

Step1: Calculate first term

$2(6 \cdot 2) = 2 \times 12 = 24$

Step2: Calculate second term

$2(6 \cdot 3) = 2 \times 18 = 36$

Step3: Calculate third term

$2(2 \cdot 3) = 2 \times 6 = 12$

Step4: Sum all terms

$24 + 36 + 12 = 72$

Answer:

72
